Намерение NFC -> получить информацию от метки

Я борюсь с NFC и намерениями, я могу обнаружить теги, но как я могу прочитать информацию из них?

Как видно из кода: я получаю обнаруженный тег с намерением: Intent {act= android.nfc.action TECH_DISCOVERED flg=0x13400000 cmp=com.example.android.apid/.nfc. Техфильтр(есть доп.)}

Я хочу получить информацию из тега, должен ли я анализировать байты и т. д.?

Лучшие регистры h.
